Electronic effects on our lives
Electronic effects on our lives
Electronics manufacturing complex components and materials, its impact on the environment is multifaceted. Computer, for example, a computer will need about 700 kinds of raw materials, raw materials, about half of these contain substances harmful to humans and the environment, most notably heavy metals, particularly lead. Each screen display tube containing about 3.6 kg of lead, the circuit board has lead. Lead and its compounds tradetang is not easy at room temperature oxidation and corrosion. As the lead into the environment can not be decomposed by icrobial metabolism, so it is persistent in the environment of pollutants. Lead to a large body Most systems are harmful, especially damage the blood system, nervous system and kidneys. and switches containing mercury and chromium compounds, chromium compounds through skin penetration by the cells, trace will cause serious allergic reactions, are more likely to wholesale car dvd players cause asthma, damage DNA; mercury will be brain damage Department of nerve. Computers are arsenic, brominated flame retardants, cadmium, PVC and other wastes. A computer contains hazardous substances that pollute the environment as much as 10 kg.Appliances also contain substances harmful effects, the environment, such as wholesale electronicsrefrigerators CFC-12 refrigerant and foaming tradetang agent CFC-l1 is the ozone-depleting substances; TV picture tube with an explosive, contain lead, mercury and other screen.In the e-waste also have a lot of waste batteries, the hazard potential and long-term. One button phone can print 10,000 liters of water (the equivalent of one’s life in the water), while an object at the dissolution of the battery is enough to make one square meter of soil loss of agricultural value.Electronic waste has become the largest metal pollution. Overseas data show that 40% of lead waste disposal sites from e-waste.
China’s consumer electronics products is for individuals and families with radio, television-related audio and video products, including: TV, DVD player (VCD, SVCD, DVD), VCRs, video cameras, radios, tape recorders, combination audio, record player, CD player (CD ) Tradetang.com And so on. In some developed countries, put the phones, wholesale car dvd, home-office equipment, , health care equipment, automotive electronic products are also in the consumer electronics products. With the technological development and the emergence of new products and applications, digital cameras, mobile phones, PDA and other products are also Into a new consumer electronics products. Since the late nineties from the twentieth century, combines computer, information and communications, consumer electronics, home appliances began three broad areas of family life deeply, which has audio-visual, information processing, two-way network communication wholesale speakers functions, by the Embedded processor, hardware-related support (such as graphics cards, storage media, IC card or credit card reader devices), embedded operating system and application-layer package composition. Tradetang.com Broadly speaking, information appliances, including all information through interactive network of home appliances,Such as PC, set-top boxes, HPC, car dvd players, super VCD, wireless data communications equipment, video game equipment, WEBTV so. Currently, audio, video and communications equipment is a major component of information appliances. In the long run, refrigerators, washing machines, microwave ovens, etc. will also be developed into a letter Information appliances, and constitute an integral part of smart home appliances
In the electronics manufacturing companies in the standard procurement process can Huafen strategic sourcing and orders for the coordination of two areas, strategic sourcing, including supplier development and management, order orchestration is the main Fuze material procurement plan, Zhong Fu Yi Ji delivery payment terms of order affairs. This organizational structure Structure and sales system is very similar to a lot of sales-based company also established a professional sales support department with a large number of repetitive orders. Supplier development and management is the core of the entire procurement system, its performance is also related to the performance of the purchasing department.
